3 Claims. (Cl. 189-76) ihis invention relates to improvements in windowassemblies. This application is a division of my application 592,340,filed May 7, 1945, Pat ent Number 2,525,322, patented October 10, 1950.

An object is to provide a window assembly including a window pane and asash therefor of improved design and novel construction and whereinopposed sash members are relatively adjustable to vary the over-alldistance established thereby.

This improved window assembly is illustrated as comprising sheet metalsash members which embrace the window pane and are secured together toconstitute a simple unitary window and sash assembly.

The sash structure includes a pair of endsash rails and a pair of sidesash rails which embrace the end and side margins, respectively, of aglass pane. At least one of the sash rails is adjustable with respect tothe pane and toward and away from the other sash rail of the pair, andmeans is provided to maintain said adjustment. The adjustable sash railis here illustrated as one of the side sash rails and means isassociated with the end sash rails to maintain its adjustment. Suchmeans preferably comprises a supplemental end sash rail which grippinglyengages the end rail of the sash and is adjustably slidable lengthwisethereover to maintain the adjustable side sash rail at differentpositions of lateral adjustment.

In the embodiment here shown, the sash structure of the character abovedescribed includes top and bottom supplemental sash rails which areslidingly adjustable over the top and bottom rails of the sash betweenthe side rails thereof and are adapted to maintain the sash side railsat adjusted positions.

Other objects, advantages, and meritorious features of the inventionwill more fully appear from the following description, appended claimsand accompanying drawing wherein:

Figure 1 is an elevation partly broken away of a window assemblyembodying this invention,

Figure 2 is a perspective of a disassembled end 7 numeral I2.

by the numeral ill. A top sash rail which is channet-shaped in crosssection is indicated by the 2 It is shown in Figures 1 and 4 asextending along and embracing the top margin of the glass pane. A bottomsash rail indicated by the numeral I4 is channel-shaped in cross sectionand is shown in Figure 1 as extending along and embracing the bottommargin of the glass pane.

A pair of side rails are indicated as [6. These side rails arechannel-shaped in cross section and are shown as extending along andembracing the side margins of the glass pane. Each side railhas one sidewall cut away at one end as shown at [8 and the opposite side wallextended and folded over the end rail and into such cut-out as shown at20. Each side rail at its end has a channel width sufficient to receivetherein the adjacent end of an end rail as shown in Figure 5 so that theend portion of the side rail overlaps the end rail.

The top sash rail is here shown as provided with a channel-shapedsupplemental sash rail 22 which is of shorter length than the sash raill2 and grippingly embraces the same, urging the same against the glasspane. This sash rail 22 is adjustable lengthwise over the sash rail 12and between the side sash rails I6 and is so grippingly engaged with thesash rail l2 as to maintain different positions of adjustmentathereover.

The bottom sash rail [4 is provided with a supplemental sash rail 24which is of shorter length than the sash rail [4 and is grippinglyengaged thereover urging the same against the glass pane. The sash rail24 is adjustable lengthwise over the sash rail I4 and between the siderails 16 H and is so grippingly engaged with the sash rail it as tomaintain its position of adjustment thereover.

In the wooden sash of commerce it is common practice to fit a sash to awindow opening by removing some of the material from the edge of thesash. Window openings vary somewhat in size and the sash rails ofcommercial window sash are generally made of greater width thannecessary in order that they can be cut down to fit window openings ofdifferent size.

With my improved metal sash the same result is accomplished in a simplemanner by positioning a side sash rail at the desired point to provide awindow sash of the required'size to fit the opening and then adjustingthe supplemental top and bottom sash rails to maintain the adjusted sidesash rail at its point of adjustment. Each side rail of the sash hereshown is capable of lateral adjustment with respect to the pane. Eachside sash rail may be advanced toward or withdrawn away from the pane land over the top and bottom sash rails l2 and 14 to increase or decreasethe width of the window assembly. Each supplemental sash rail is adaptedto be adjusted over the end sash rail embraced by it to engage at itsend a side sash rail to maintain the sash side rail at the position towhich it may have been adjusted with respect to the pane and withrespect to the top and bottom sash rails of the sash.

When the adjustment of a side sash rail to fit the window opening hasbeen accomplished the supplemental end sash rails are then adjusted overthe end sash rails until each supplemental sash rail engages at one endthe adjusted side sash rail as shown at the right at the top of Figure 1and in dotted outline in Figure 4. The adjusted side sash rail ismaintained at its position of lateral adjustment with respect to the endrail of the sash by the end engagement of the supplemental sash railstherewith.

What I claim is: a

1. A window comprising, in combination with a window pane, achannel-shaped sash top rail extending along and embracing the upperedge of the window pane, a channel-shaped sash bottom rail extendingalong and embracing the lower edge of the window pane, a pair ofchannel-shaped sash side rails extending along and embracing theopposite side edges of the window pane and overlapping the end portionsof the top and bottom rails, each side rail of the sash being adjustabletoward and away from the pane, a supplemental channel-shaped top railextending along and embracing the top rail of the sash between the sidrails thereof, a supplemental channel-shaped bottom rail extending alongand embracing the bottom rail of the sash between the side railsthereof, each supplemental rail being adjustably slidable lengthwiseover the sash rail embraced thereby and adapted to engage theoverlapping end of a side rail of the sash to maintain the side rail atlaterally adjusted positions with respect to the glass pane.

2. In a window and sash assembly, a window pane, a frame for the paneincluding a pair of end sash rails extending along and embracing the twoend margins of the pane and a pair of side sash rails extending alongand embracing the two side margins of the pane, the two members of onepair of sash rails being relatively adjustable toward and away from eachother to different spaced apart positions of adjustment with respect tothe two members of the other pair of rails, a pair of supplementalchannelshapsd rail members extending along and grippingly embracing thetwo members of said other pair of rails each supplemental rail beingrelatively adjustable lengthwise over the rail it embraces into abuttingcontact at one end with one of the adjustable sash rails to maintain thesame at its adjusted position.

3. In a window and sash assembly, a window pane, a channel-shaped topsash rail extending along and embracing the top margin of the pane, achannel-shaped bottom sash rail extending therealong and embracing thebottom margin of the pane, a pair of channel-shaped side sash railsextending along and embracing the side margins of the pane andoverlapping the top and bottom sash rails and folded over the top andbottom margins thereof, at least one of the side sash rails beingadjustable laterally with respect to the pane and relative to the topand bottom sash rails, a channel-shaped supplemental top rail extendingalong and embracing the top sash rail and adjustable lengthwisethereover between the top end portions of the side rails into abuttingengagement with the adjustable side sash rail and a channel-shapedsupplemental bottom rail extending along and embracing the bottom sashrail and adjustable lengthwise thereover between the bottom end portionsof the side rails into abutting engagement with the adjustable side sashrail.
